摘要： A cutting tool formed by a coating layer on a substrate has cutting edges that feature serrations. The linear dimensions of the serrations may vary from a few nanometers up to 10 microns. The serrations result in a smoother cut edge on the workpiece, particularly when the workpiece is formed of certain materials that are seen as particularly difficult to cut, such as hardened steels.

摘要： A cutting insert (1) includes an end cutting edge (5a) located along an intersection of an upper surface (2) and a front clearance surface (4a), and a pair of side cutting edges (5b) respectively located along intersections of the upper surface (2) and a pair of side clearance surfaces (4b). The upper surface (2) includes an end rake surface (21a) that is continuous with the end cutting edge (5a) and is inclined downward as departing from the end cutting edge (5a), a pair of major protrusions (22a) that are located apart from the end cutting edge (5a) and are less apart from each other as departing from the end cutting edge (5a) in a top view, and a pair of minor protrusions (22d) that are respectively located close to their adjacent side clearance surface (4b) of the pair of side clearance surface (4b) with respect to the pair of major protrusions (22a) in the top view. The pair of minor protrusions (22d) are located further apart from the end cutting edge (5a) than an end portion of each of the pair of major protrusions (22a) which is close to the end cutting edge (5a). A top portion of each of the pair of minor protrusions (22d) is lower than a top portion of each of the major protrusions (22a).

摘要： The invention relates to a cutting insert (1) for the machining of workpieces, comprising a cutting edge (40) and an adjoining rake face (41), which are formed by an ultra-hard layer (4) made of diamond or cubic boron nitride. A chip-guiding groove (44) designed as a depression in the ultra-hard layer (4) is provided in the rake face (41). A chip-influencing element (5) made of a hard material is arranged on the side of the chip-guiding groove (44) furthest from the cutting edge (40) and protrudes above the surface of the ultra-hard layer (4). In a radial direction running from a cutting corner (42) to a centre (Z) of the cutting insert the chip-influencing element (5) is arranged spaced from the chip-guiding groove (44).

摘要： The invention relates to a double-sided, indexable turning insert having a polygonal basic shape, comprising a plurality of corners, a peripheral clearance surface, and identical upper and under sides, in which there are included support surfaces situated in a reference plane, which are parallel to each other and to a neutral plane, which is situated halfway between the reference plane and toward which the clearance surface extends at a right angle. Along the upper side as well as the under side, primary cutting edges (12) are present, which individually include a nose edge (14) situated in a corner and two main edges (15), which converge toward the same and are located in a nose plane inclined in relation to the neutral plane, and which transform into auxiliary cutting edges (19), which run parallel to the neutral plane and separate each pair of primary cutting edges along one and the same side of the turning insert, chip-directing guide surfaces (24, 25, 21) being placed inside the chip surfaces (16a, 16b, 16c) of the cutting edges. According to the invention, the primary cutting edge (12) has a generally positive cutting geometry so far that a wedge angle of the cutting edge between the chip surface (16a) and the clearance surface is acute in arbitrary sections along the nose edge (14) as well as along the two main edges (15). In such a way, the primary cutting edge becomes easy-cutting and produces chips that can be guided in a careful, although distinct way by the guide surfaces being inside.

摘要： This invention relates to a polygonal turning insert having primary cutting edges (12), which individually include a nose edge (14) and two main edges (15), which converge toward the same. Behind the nose edge, chip-directing guide surfaces are formed, viz., on one hand, a breast surface (24) included in a knob (20) situated behind the nose edge along a bisector between the main edges (15), and, on the other hand, a pair of flank surfaces (21) included in a land being behind. According to the invention, at a distance behind the knob (20), there is formed a second breast surface (25), the upper part of which is situated on a higher level than the upper part of the first breast surface (24). In such a way, it is guaranteed that thin chips, which tend to pass or jump over the first breast surface without being affected by the same, will impinge on the second, higher breast surface and be subjected to guiding by the same.

摘要： A cutting insert according to an embodiment of the present invention includes an insert body including an upper surface, a lower surface, a side surface connected to each of the upper surface and the lower surface, and a cutting edge located at an intersection of the upper surface and the side surface. The insert body is divided into a cutting section and a fixing section. A region of the upper surface located at the cutting section includes a rake surface which is located further inward than the cutting edge and is inclined as going inward at an inclination angle ±1 with respect to a reference plane perpendicular to a central axis, and a plurality of protruded parts arranged along the cutting edge. Each of the plurality of protruded parts includes a first surface which is inclined as going inward at an inclination angle ±4a with respect to the reference plane and has a larger width as going inward in a top view. The inclination angles ±1 and ±4a satisfy a relationship of ±1>±4a. A cutting tool with the cutting insert, and a method of manufacturing a machined product by using the cutting tool are also provided.

摘要： The present invention relates to a cutting insert which is capable of carrying out cutting efficiently at high accuracy over a longer period of time on medium cutting of a difficult-to-cut material such as stainless steel by preventing in particular plastic deformation which occurs at a part extending to the side opposite of a feed direction from a corner section of a cutting edge. The cutting insert is provided with a ridge section between a rake face (2) and a flank face (3) in an insert main body (1) with a cutting edge (5) having a corner section (6) which forms a convex arc shape when seen in a planar view from the direction facing the rake face (2) and a pair of linear sections (7) that are in contact with the corner section at the both ends of the corner section and extend linearly. The cutting edge (5) is provided with a first region (A) along the corner section (6), a second region (B) along the linear section (7) and a third region (C) positioned between them, and a cross-sectional area of the insert main body (1) on a cross-section orthogonal to the cutting edge (5) in a range of width which is a radius R (mm) of the corner section (6) perpendicular to the cutting edge (5) toward the inside of the rake face (2) is made largest in the third region (C), smallest in second region (B) and between them in the first region (A) in terms of size.
